摘要: 为验证整体匹配优化设计效果, 以某典型水下航行器动力推进系统仿真模型为例, 通过建立其有限元简化模型, 基于多目标遗传算法(Multi Objective Genetic Algorithm, MOGA), 选取联轴节与尾轴长度比、尾轴支承位置以及支承刚度作为参数变量, 以壳体上四处关键位置的振动能级作为目标函数, 分别进行参数变量单独优化与整体匹配优化。结果表明, 可通过调整联轴节与尾轴长度比、改变尾轴支承位置和支承刚度等措施来优化系统振动响应, 其中联轴节与尾轴长度比优化后的减振效果可达5.2 dB, 而整体匹配优化相比各参变量单独优化效果更为显著, 其振动能级落差可达9.2 dB。最终得出结论在动力推进系统支承参数优化过程中, 各参数之间可通过多目标遗传算法进行匹配优化, 可最大程度降低系统整体振动响应水平。整体匹配优化方法可为水下航行器动力推进系统的减振优化设计提供新的优化思路。Abstract: To verify the effect of the overall matching optimization design, this study takes the simulation model of a typical underwater vehicle Power Propulsion System (PPS) as an example. By establishing its finite element simplified model and based on the Multi Objective Genetic Algorithm (MOGA), the length ratio of the coupling to the tail shaft, the support position of the tail shaft, and the support stiffness are selected as parameter variables. The vibration levels at four key positions on the shell are used as the objective functions to carry out separate optimization of parameter variables and overall matching optimization respectively. The results show that the vibration response of the system can be optimized by adjusting the length ratio of the coupling to the tail shaft, changing the support position and support stiffness of the tail shaft, etc. Among them, the vibration reduction effect after optimizing the length ratio of the coupling to the tail shaft can reach 5.2 dB, while the overall matching optimization is more significant than the separate optimization of each parameter, with the vibration level drop reaching 9.2 dB. Finally, the conclusion is drawn that in the process of optimizing the support parameters of the power propulsion system, each parameter can be matched and optimized through a multi-objective genetic algorithm to minimize the overall vibration response level of the system. The overall matching optimization method can provide a new optimization idea for the vibration reduction optimization design of the power propulsion system of underwater vehicles.
